I had this problem, try decreasing the temp of your oven by about 10 degrees and also if your oven is fan forced line the pan with baking paper so it comes up nice and high and protects the rising cake from the flow of air from the fan.

I also notice you didn't line the tin with paper. Did you grease and flour it well? Sometimes not doing that will cause the cake to have trouble 'rising' because its cooked to the edges and that causes cracks.

Looking at your cake, I think this may be more likely because the cracks are around the rim. Cracks from too hot an oven tend to be in the centre with more of a volcanic protrusion.

I greased the tin and lined the base with paper but not the sides. I just turned the cake out and it's come out perfectly. yay!

Yep I followed the recipe.

ETA - greenthumbs - I only cleaned the oven last week, we're in a rental while our house is being built so trying to make the move out clean as painless as possible. Lucky you can't see the rest of the kitchen though. lol
